CO2.Earth is now live. I am proud that it is one of the very first websites on the internet with a .earth domain. The first .earth site to launch—democracy.earth—happened last week. This week, CO2.Earth is the site that's rolling out, just before .earth domains open for public registration on December 19, 2015.

Also, just in time for the international climate summit in Paris, CO2.Earth takes over global redistribution of CO2 data from CO2Now.org.

CO2.Earth is here to track the atmospheric CO2 trend along with you. Any time you want an update for earth's planetary vital signs, CO2.Earth points to the latest numbers.

-0.67°C -1.21°F

The January 2018 temperature across global land and ocean surfaces was 0.71°C (1.28°F) above the 20th century average of 12.0°C (53.6°F). January 2018 marks the 42nd consecutive January (since 1977) and the 397th consecutive month (since January 1985) with temperatures at least nominally above the 20th century average. This was the fifth highest temperature for January in the 1880–2018 record. The last four years (2015–2018) rank among the five highest Januarys on record. The global land and ocean temperature during January has increased at an average rate of +0.07°C (+0.13°F) per decade since 1880; however, the average rate of increase is twice as great since 1975.

La Niña was present across the tropical Pacific Ocean during January 2018. According to NOAA's Climate Prediction Center, A transition from La Niña to ENSO-neutral will most likely occur during the Northern Hemisphere spring (Southern Hemisphere autumn). [NOAA global analysis accessed March 12, 2018].

"The science is sobering—the global temperature in 2012 was among the hottest since records began in 1880. Make no mistake: without concerted action, the very future of our planet is in peril."

NOAA's global analysis: "2016 became the warmest year in NOAA's 137-year series. Remarkably, this is the third consecutive year a new global annual temperature record has been set. The average global temperature across land and ocean surface areas for 2016 was 0.94°C (1.69°F) above the 20th century average of 13.9°C (57.0°F), surpassing the previous record warmth of 2015 by 0.04°C (0.07°F). The global temperatures in 2016 were majorly influenced by strong El Niño conditions that prevailed at the beginning of the year.

This marks the fifth time in the 21st century a new record high annual temperature has been set (along with 2005, 2010, 2014, and 2015) and also marks the 40th consecutive year (since 1977) that the annual temperature has been above the 20th century average. To date, all 16 years of the 21st century rank among the seventeen warmest on record (1998 is currently the eighth warmest.) The five warmest years have all occurred since 2010.

Overall, the global annual temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880 and at an average rate of 0.17°C (0.31°F) per decade since 1970." [NOAA global analysis for 2016 accessed March 6, 2017].

"Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been greater than the old record by this much."

Before the end of 2015, scientists projected that average global temperature increase for 2015 will exceed 1°C above pre-industrial levels. The years 1850-1990 are used as the pre-industrial baseline by the MET Office and Climate Research Unit at the University of East Anglia in the UK. The MET Office released this statement in November 2015:

"This year marks an important first but that doesn't necessarily mean every year from now on will be a degree or more above pre-industrial levels, as natural variability will still play a role in determining the temperature in any given year. As the world continues to warm in the coming decades, however, we will see more and more years passing the 1 degree marker - eventually it will become the norm."
